Question

用户在我的rails db schema中有许多配置文件，例如admin和merchant等。现在我如何编写代码来检查当前用户是否是管理员？更多信息：用户表是独立的，配置文件表是分开的。它们通过has_and_belongs_to_many：profiles

在用户模型中链接

这是我的架构：

 create_table "profiles", force: true do |t|
    t.string   "name",        null: false
    t.string   "description"
    t.datetime "created_at"
    t.datetime "updated_at"
 end

  add_index "profiles", ["name"], name: "index_profiles_on_name", unique:     true, using: :btree

  create_table "profiles_roles", id: false, force: true do |t|
    t.integer "profile_id"
    t.integer "role_id"
  end

  create_table "profiles_users", id: false, force: true do |t|
    t.integer "profile_id"
    t.integer "user_id"
  end

  create_table "role_types", force: true do |t|
    t.string   "name"
    t.string   "description"
    t.datetime "created_at"
    t.datetime "updated_at"
  end

  create_table "roles", force: true do |t|
    t.string   "name",         null: false
    t.string   "description"
    t.datetime "created_at"
    t.datetime "updated_at"
    t.integer  "role_type_id"
    t.string   "display_name"
  end

  add_index "roles", ["name"], name: "index_roles_on_name", unique: true, using: :btree

create_table "users", force: true do |t|
    t.string   "username",                       default: "",    null: false
    t.string   "encrypted_password",             default: "",    null: false
    t.string   "email",                          default: ""
    t.string   "reset_password_token"
    t.datetime "reset_password_sent_at"
    t.datetime "remember_created_at"
    t.integer  "sign_in_count",                  default: 0
    t.datetime "current_sign_in_at"
    t.datetime "last_sign_in_at"
    t.string   "current_sign_in_ip"
    t.string   "last_sign_in_ip"
    t.datetime "created_at"
    t.datetime "updated_at"
    t.string   "first_name"
    t.string   "last_name"
    t.string   "msisdn"
    t.string   "city"
    t.string   "address"
    t.integer  "e_bills_count",                  default: 0
    t.string   "notification_url"
    t.string   "notification_params",            default: [],                     array: true
    t.boolean  "notification_post",              default: true
    t.string   "legal_info"
    t.string   "greeting_message"
    t.boolean  "email_notification",             default: false
    t.string   "website"
    t.string   "logo"
    t.string   "signature"
    t.string   "additional_notification_params", default: ""
    t.string   "currency"
  end

没有单一的教条式的“轨道式”和＃39;去做这个。最简单的方法是添加一个布尔列＆＃39; is_admin＆＃39;。但是因为这不适合其他场景，所以这通常会扩展到一个有额外角色的架构。 table和与用户模型的has_many关系。

Thare也是更复杂的授权模型的宝石：

示例实现可以是：

self.profiles.map(&:name).include?('admin')
